Chris Gayle denies exposure reports

West Indies cricketer Chris Gayle says he was devastated by false and humiliating Fairfax Media claims that he exposed his genitals to a massage therapist.

Giving evidence in a Sydney court on the first day of his defamation trial, the 38-year-old denies he asked massage therapist Leanne Russell whether she wanted to "touch me up, baby".

He agreed he had appeared in a condoms advertisement in which he declared: "I'm a bad boy with women."

He also agreed that in the lead-up to the Fairfax stories he had been criticised for inviting reporter Mel McLaughlin to have a drink after a Big Bash game and telling her "Don't blush baby" during a live TV interview.

In the NSW Supreme Court on Monday, his barrister, Bruce McClintock SC, told the four-person jury that Fairfax had set out to "destroy" the cricketer in a "vicious, savage and false attack" published in three of its newspapers from January 2016.

Gayle says the articles falsely claimed he intentionally exposed his genitals to, and indecently propositioned, Ms Russell in the West Indies dressing room during a Sydney training session at the 2015 World Cup.

Gayle told the jury the claims were the "most hurtful thing I've actually come across in my entire life".
